SPECIFICATION forming part of Letters Patent N0. 777,967, dated December 20, 1904.

Application filed February 8, 1904:. Serial No. 192,516.

T0 ir/ZZ whom, it may concern.-

Beit known that I, JONATHAN MCO. LorER, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification, reference being had therein to the accompanying drawings.

This -invention has relation to horseshoes, and relates in particular to horseshoes having removable calks.

The object of my invention is to provide means for applying to a shoe of the ordinary character either a supplementary shoe having integral calls formed thereon or independent calks for the heel and point of the shoe.

My invention has for its further object the provision of means for protecting the foot of the horse from injury, said protective means being combined and operating in connection with the supplementary shoe or the independent calks above mentioned.

The invention consists in the combination, with a shoe of the ordinary character, of attachable calls which are either formed on and of a single integral piece constituting the supplementary shoe or they may be independent pieces, each of which may be independently attached to the shoe, said calks or supplem'entary shoe carrying said calls being provided with integral cars adapted to embrace the edges of the shoe and assist in connection with suitable screws in maintaining the callis or the supplementary shoe in proper position.

My invention further consists inthe combination, with a shoe havinga supplementary shoe formed with integral calks or independent calks, of a plate of metal or other suitable material conforming in outline to the contour of the shoe and interposed between the shoe and the supplementary shoe or the independn ent calks, as the case may be, and held in position by the devices which secure the supplementary shoe or independent calks to the ordinary shoe.

My inventionfurther consists in the novel construction, combination,and arrangementof parts to be hereinafter described and claimed.

In the drawings, Figure l is a plan view looking at the bottom of a horseshoe of the ordinary character having independent calls and a frog-protecting plate applied thereto. Fig. 2 is an edge view of the same. Fig. 3 is a top plan view of the shoe shown in Figs. l and 2. Fig. 4 is a bottom plan View showing a modified form of my improvement in which the attachable callis are formed integral with thc supplementary shoe, Fig. 5 is an edge View of the device shown in Fig. 4, and Fig. 6 is a top View of the same.

' Referring iirst to Fig. l, A designates a horseshoe of the ordinary character having Hat calks B B at the heel and a iiat calli O at the toe thereof. E E designate supplementary calls which are formed with sharp projecting portions F F, the said calks being of slightly greater width than the width of the portion of the shoe A to which they are attached and provided with upwardly-turned ears Gr G, which tightly embrace the sides of the shoe to which the callzs are attached, being hammered into firm contact therewith after the callzs are placed in position. B olts H H pass through the calls and screw into the shoe A and serve in connection with the upturned ears F to maintain the calks in rigid position on the shoe. Within the toe-calli() is arranged another supplementary cal k, I, which has a straight upper edge that bears against the call; C, and two curved ends J J, the inner edge of the call; I preferably conforming to the contour of the inside edge of the shoe A. The call( I is provided with an integral sharp-edged projecting part K and is secured to the shoe by means of bolts L L, passing through the calli near its ends and screwing into the shoe A. A flat plate M, of metal or other suitable material, such as rubber or leather, which is shaped to conform to the outline of the shoe A, is located between the bottom of the shoe and the calks E E and I, the said plate being formed with slots N N for the passage of the ears G Gr on the inner sides of the callrs E E and the bolts H H and L L passing through suitable holes in the said plate, the plate being thus iirmly held in position against the bottom of the shoe A and serving to prevent injury to the horses foot or contact with the ice or snow on the roadway.

In the construction shown in Figs. 4, 5, and 6 I have substituted for the independent calks E E and I of Figs. 1, 2, and 3 a supplementary shoe O, which is secured to the bottom of the ordinary shoe by screws P P and which has calks R at the heel and a call( S at the toe formed integral with said supplementary shoe. The supplementary shoe, which, it is to be understood, is to be substantially the same in construction, mode of application, and operation of the calks E E and I, is formed with upturned ears T T, which conform to the upturned ears G of the callrs E E and are similarly operated upon, being driven into firm contact with the body of the shoe proper after the supplementary shoe O has been placed in position thereon. A plate U, conforming in character to the plate M, is interposed between the shoe proper and the supplementary shoe O, and slots VV are formed in said plate for the passage oi' the inner ears T T of the supplementary shoe.

The calks E E and I in the one instance or the supplementary shoe O in the other are, it will be noted, readily attachable to the shoe of the ordinary character, the only alteration necessary in such ordinary shoe being' to bore and thread holes for the reception of the bolts H and L or the screws P, as the case maybe. It is to be noted, moreover, that the calks E E and I or the supplementary shoe, with its calks R and S, may be readily detached from the shoe proper and the points of the callas sharpened when necessary, or if entirely worn out the calks or the supplementary shoe may be replaced by new parts.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with a horseshoe having integral calks and screw-threaded holes adjacent to said calks, of removable calks having integral upturned ears on both edges, said removable calks abutting said integral ealks, a plate fitting between the shoe and the calks and formed with slots to receive the ears on the inner edges of the calks and bolts passing through the removable callrs and the plate and screwing into the holes in the shoe.

In testimony whereof` I aflix my signature in the presence of two witnesses.
